Swisscom
Swisscom is Switzerland's largest telecommunications provider and the incumbent mobile network operator, fixed-line carrier and IT services company for the Swiss market, majority-owned by the Swiss Confederation and also operating Fastweb in Italy. In the telecom value chain it is a facilities-based MNO that owns the radio access and core network, sells mobile, broadband, TV and enterprise IT, and monetises network-derived data. Its API posture is unusual for a European incumbent: alongside the expected partner-gated enterprise surface it runs a genuine first-party API marketplace at digital.swisscom.com listing ten productive API products (SMS, SMS token 2FA, inbound SMS, mobility heatmaps, dwell times, origin-destination, NATEL go smart catalogs, AI inference endpoints and a business identity validator) served from a live api.swisscom.com gateway, plus a separately maintained, actively released Swisscom Sign Integration API with a downloadable OpenAPI 3.1 document. The catch is that every API reference, key and spec beyond Swisscom Sign sits behind a Swisscom login and, for several products, a signed service contract — the marketplace is a storefront, not open documentation. On network APIs Swisscom was one of the 21 founding signatories of the GSMA Open Gateway Memorandum of Understanding in February 2023, but it publishes no CAMARA API, no Open Gateway developer portal and no callable network-API endpoint; developers who want SIM-swap or phone-verification signals from the Swisscom network have historically reached them through third-party channels such as IPification rather than from Swisscom directly. Its legacy developer programme (developer.swisscom.com, the Cloud Foundry Application Cloud, the swisscom-developer GitHub SDKs) is dead or redirected, and the older Messaging and Voice APIs are still documented only as RAML-rendered HTML in a GitHub wiki.
Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.
API Evangelist profiles Swisscom the way a machine reads it — 23 machine-readable artifacts across 2 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Swisscom scores 64.9/100 (strong), with a separate agent-readiness read of 46/100 (agent ready). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Swisscom
Each block below is one kind of artifact we hold for Swisscom. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 14
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

ASYNCAPISecurity Posture 4
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

SECURITYScopes 1
OAuth scopes are the vocabulary of least-privilege access. Profiling them shows exactly what an integration — or an agent acting on a user's behalf — is allowed to do.
OAuth scopes governing access to this provider's APIs.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.

This is an independent, third-party profile of Swisscom, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
